False advertising

They Thrive on false advertising.I bought a a SIM card it arrived on the 22nd of October for R169 for unlimited Telkom Lte .On the first they sent a new invoice that I owe them money I just bought the SIM card and it was supposed to last me a month long according to the ad yesterday they closed the data . R169 gone down the drain and they have the audacity to send an email that they'll cancel Thier services. If I don't pay R232 that means they expecting me to pay R400 for a SIM card they had advertised at R299 per month.... Yoh guys y'all think we go to work for y'all neh in this economy y'all think we just have spare money to give away neh mxm
